Modern climatic conditions compel mankind to look for new sources of air purification. Apartment buildings are practically airtight and do not have effective ventilation. In this regard, the oxygen concentration in the room decreases and, accordingly, the mental and physical activity of residents decreases.
The only solution today is to create forced ventilation. The rooms are equipped with special devices with supply air valves. Such air conditioners with an influx of air from the street usually deliver no more than 40% of the air to the room.
The need for fresh air
It is no secret that fresh air is vital for maintaining health. Therefore, manufacturers in the field of climate technology began to pay more attention to ventilation problems. Every living creature needs oxygen, but because of the pace of modern life, people forget to take care of themselves, which leads to poor health and illness. The purchase of an air conditioner with a fresh air flow mode will make it possible to work efficiently throughout the day in a closed room.
Why constant micro-ventilation is needed:
- Constant air changes increase the level of oxygen in the room.
- Oxygen has a positive effect on metabolism and the functioning of the respiratory and immune systems.
- Pressure stabilization occurs and heart function improves.
- Thanks to oxygen, the level of stress is reduced and the brain works more efficiently.
The consequences of a lack of oxygen:
- The general health worsens, a malaise appears.
- Pressure rises and headache rises.
- Irritability and constant fatigue appear.
Modern air conditioning performs not only the function of cooling the air. It simultaneously serves as a cleaning system, a heating device, can supply air to the room.
The main task of the split system is to ensure comfortable living conditions.
Types of split systems with a mixture
An air conditioner with air inflow from the street differs from the classic split system by the presence of a separate duct channel. Models of this type differ in the structure of this channel.
Consider the types of air conditioners:
- With a membrane. Such an air conditioner is equipped with a membrane, it is she who is responsible for the operation of the channel. Feature: uneven throughput. The membrane is designed so that oxygen passes through it better than other gases. Such devices are quite expensive and rarely found on the market.
- Modular system. This is an addition to the existing system in the form of a recuperator with an air duct. It is equipped with an external unit and is installed outdoors next to the air conditioner. The module has two tubes, with the help of which there is an air exchange and thermoregulation. Minus: overall external unit and small air exchange. The modern market almost does not sell such structures, since they are significantly inferior to analogues.
- Modified external unit. This solution is the most logical and is a combination of cooling and ventilation units. Between the external and internal parts of the air conditioner, a duct is installed for oxygen supply. Minus: high cost and average air exchange (the amount of ventilated oxygen is calculated for the presence of only one person in the room).
The price of air conditioners with air flow from the street starts at 30 thousand rubles. and depends on the required functionality.
Also on sale you can find modifications of these types of systems. But all of them have a drawback - a low rate of air exchange. Channel systems give a better result, but their installation is difficult for an ordinary apartment.
Channel Split Systems
The channel air conditioner with fresh air from the street is a hidden system that effectively performs the function of ventilating the room. Such devices can be installed during the repair phase in the apartment, but still they are more designed for industrial use.
Features:
- The system is designed to install several indoor units built into the ceiling. Outside, a grill or diffuser is installed to supply and intake air masses.
- For efficient operation, the system needs a fan of high power, which exceeds the split system in terms of noise.
Thus, before installing the channel system, you need to consider all the options, evaluate the positive and negative points.
How air conditioning works with inflow
Despite the shortcomings, the most optimal solution is to install separate cooling and ventilation units. An efficient air conditioner with air flow from the street delivers up to 160 m 3 / h of oxygen. At the same time, the system cleans it of impurities and unpleasant odors. Any channel air conditioner or split system with air supply is equipped with an air duct. The first type is usually equipped with a water or electric heater for heating the incoming air.
Air conditioning with ventilation consists of:
- Indoor unit. It is equipped with a fan, a heat exchanger, a filtration system and an electronic control unit.
- Outdoor unit. It contains a compressor, a cooling fan, a condenser heat exchanger, a mixing chamber and an additional suction turbine.
Air mixing process:
- The fan draws in air from the street and transfers it through the air duct to the indoor unit.
- Then the masses enter a separate chamber, where they are mixed with room air.
- Then the mixed air passes through the filtration system and, if necessary, is heated / cooled / dried / humidified.
- After all the steps, air enters the room.
The user independently controls the level of air supply and the strength of the air flow.
Hitachi Street Air Conditioner
The most popular among the products of this manufacturer is the Air Exchanger series. These air conditioners are also distinguished by the presence of a modern Nano Titanium filter, which is capable of capturing formaldehyde and bacteria besides dust, as well as cleaning the air of odors.
When the night mode is on, the air conditioner independently regulates the temperature and humidity in the room. The system has a built-in pollution analyzer, which provides information on the freshness and purity of air.
Principle of operation: when laying the freon route, a hose is additionally installed for supplying air masses. The external and internal units are equipped with fans for oxygen supply. Due to this design, additional noise is generated in the room.
Such air conditioners have an inverter type of control. This ensures the efficiency of the models and the smooth operation of the device.
Features of Hitachi conditioners:
- High work efficiency.
- Inverter power control.
- Nanoparticle filter.
- Ozone-safe 410th Freon.
- Ability to work in a wide range of temperatures.
- Microcell fine filter.
- Air quality sensor.
Daikin air conditioners with a mixture of air
Among Daikin products, the Ururu Sarara series is popular. These are modern models equipped with the latest technology. Air conditioners are quite expensive, but one such device can replace several. These are not just air conditioners, but also effective cleaners and moisturizers.
Feature of the models: the system, which is responsible for the air supply, is located in the external unit, which minimizes the noise of the working device.
Principle of operation: air masses from the street pass through a filter located in the outdoor unit. Then they enter the cassette blades from zeolite (a hygroscopic material that provides moisture transfer), which direct air to the heating zone.
Features:
- In automatic mode, the split system independently adjusts the humidity in the room.
- The kit provides an 8-meter reinforced hose, which is created from an antibacterial material.
- Air flows through the finest filters.
- Timer control.
- 3D air flow.
- Turbo mode and wide-angle blinds.
Reviews
Since the described technology is quite new, there are also few reviews about it. Those who tested the air conditioners with the main mode of fresh air supply, emit special noise system split - from 23 to 30 dB. Such noise is not always convenient for residents of apartment buildings. Many customers consider the humidification function to be unimportant, because you can not overpay, but purchase a humidifier separately (cheaper).
More attention is paid to cleaning filters, because it is on them that the clean air in the room depends. This is especially true for people with allergies.
Customers also prefer air conditioners from trusted manufacturers with a high warranty period.
The disadvantage is the inability to use a mixture of air in many models at temperatures below +18 degrees Celsius. It turns out that air conditioning is a summer option.
To summarize
So, we can safely say that air conditioners with air flow from the street occupy a special segment of the market. Modern living conditions and air pollution are forcing to look for new ways to maintain human health. Air conditioning is necessary both in the office and at home to maintain the necessary level of physical and mental activity.
The modern split system not only helps to cool the air, but also has a wide range of functions: heating, cleaning, humidity control, a mixture of atmospheric air, a timer and others.
